However, all hidden songs from copula's events (開通！とことこライン, Season Line, おてがる！！LINK TRACK, Mystery Line) are still hidden if you did not unlock them on copula.

Hidden songs not unlocked can be currently be played with mystery scrolls (秘術の書, or Hijutsu no sho), which were added to the game on November 17th, 2016. They work the same way as Rainbow Tickets from copula.

copula song unlocks can currently be purchased as of December 14th, 2016 with BUZZ using Kiran no omamori (金襴のお守り, "Amulet of Wealth") items.

Mystery scrolls stopped being sold on December 10th, 2017.

The result screen for ONE MORE EXTRA STAGE now shows "ONE MORE EXTRA STAGE RESULT", instead of "ONE MORE STAGE RESULT" from the previous versions.

BUZRA ARTS

BUZRA ARTS is beatmania IIDX 24 SINOBUZ's EXTRA STAGE system. For Japanese version machines, this only appears on PREMIUM START (which requires PASELI). The event began on December 1st, 2016.

BUZRA is a portmanteau of "(SINO)BUZ" and "Vajra". The songs are related to the seven SINOBUZ elements: Fire, Water, Wood, Metal, Earth, Brightness and Darkness. New BUZRA ARTS songs appeared every six weeks for the first four songs:

FIRE - December 1st, 2016

WOOD - January 12th, 2017

EARTH - February 23rd, 2017

BRIGHTNESS - April 6th, 2017

WATER - June 8th, 2017

DARKNESS - August 3rd, 2017

METAL - October 5th, 2017

Like Spada†leggendaria and Season Line, sum of difficulty levels, rank, and clear type are the main requirements to unlock a BUZRA ARTS song for EXTRA STAGE. This time, though, all the charts are playable from the first day of a BUZRA ARTS song's appearance. RANDOM cannot be used.

The conditions to access BUZRA ARTS change based on the phase it is in:

Phase 1:

NORMAL difficulty: Obtain at least an A rank on three songs that total 24 or more in difficulty by clearing them with the EX-HARD gauge.

HYPER difficulty: Obtain at least a AA rank on three songs that total 30 or more in difficulty by clearing them with a FULL COMBO.

ANOTHER difficulty: Obtain at least a AAA rank on three songs that total 34 or more in difficulty by clearing them with a FULL COMBO.

Phase 2:

NORMAL difficulty: Obtain at least an A rank on three songs that total 21 or more in difficulty by clearing them with the HARD gauge.

HYPER difficulty: Obtain at least a AA rank on three songs that total 27 or more in difficulty by clearing them with the EX-HARD gauge.

ANOTHER difficulty: Obtain at least a AAA rank on three songs that total 31 or more in difficulty by clearing them with the EX-HARD gauge.

Phase 3:

NORMAL difficulty: Obtain at least a B rank on three songs that total 18 or more in difficulty by clearing them with the regular gauge.

HYPER difficulty: Obtain at least an A rank on three songs that total 24 or more in difficulty by clearing them with the HARD gauge.

ANOTHER difficulty: Obtain at least a AA rank on three songs that total 28 or more in difficulty by clearing them with the HARD gauge.

Phase 4:

NORMAL difficulty: Obtain at least a B rank on three songs that total 15 or more in difficulty by clearing them with the regular gauge.

HYPER difficulty: Obtain at least an A rank on three songs that total 21 or more in difficulty by clearing them with the regular gauge.

ANOTHER difficulty: Obtain at least a AA rank on three songs that total 25 or more in difficulty by clearing them with the regular gauge.

Phase 5:

NORMAL difficulty: Obtain any rank on three songs that total 12 or more in difficulty by clearing them with the regular gauge.

HYPER difficulty: Obtain at least a B rank on three songs that total 18 or more in difficulty by clearing them with the regular gauge.

ANOTHER difficulty: Obtain at least a A rank on three songs that total 22 or more in difficulty by clearing them with the regular gauge.

When a BUZRA ARTS song is unlocked, the song menu's background changes and a unique background music (by HuΣeR) is played.

LAST ARTS update: From October 5th, 2017, similar to beatmania IIDX 23 copula's Season Line event, BUZRA ARTS song charts can be unlocked by clearing them once (ASSISTED EASY, as of October 26th, 2017, works). Doing so also nets you a "Buzra Icon" related to the event songs, as well as Tran Medals. Obtaining all these icons on a specified difficulty will unlock the event's secret final song on that same difficulty as a ONE MORE EXTRA STAGE. Clearing it unlocks the chart for regular play.

When the ONE MORE EXTRA STAGE is accessed, all the Buzra Icons are lost and must be obtained again. However, unlike Season Line, you can get them by clearing the BUZRA ARTS songs outside of EXTRA STAGE.

The process appears when you find items to unlock songs' charts during the course of the event.

The objective of the event is to conquer castles from enemies; to do so you must obtain Onigiri. Like 開通！とことこライン, playing a song gives you Onigiri points; the amount of points depend on which mode you are playing:

STANDARD / Dani nintei / HAZARD: 250 points (from 1 to 4 songs)

STEP UP: 333 points (3 songs)

FREE: 500 points (2 songs)

PREMIUM FREE: 250 points for the first five songs, 20 for each additional song

FREE PLUS: 500 points (3 songs)

TIME FREE: 500 points for the first 2 songs, 20 for each additional song

TIME FREE PLUS: 500 points for the first 3 songs, 20 for each additional song

TIME HAZARD: 250 points for the first 4 songs, 20 for each additional song

In STANDARD mode you'll ultimately earn less Onigiri points per play session if you have no access to EXTRA STAGE, remember. Also, using the 秘術の書 (Hijutsu no sho, purchasable with PASELI like the Rainbow Tickets) will give additional Onigiri points.

Inside the castle you can perform the following actions that require 450 Onigiri points:

Search: explore the castle to find enemies. Once the exploration rate of a castle is at 100% you cannot use this command.

Event: activate events you found during the search, be them being items or enemy fights.

Annual contribution: every 5 minutes of not playing the game you earn one Onigiri point; limit of earned points is 2000.

Ninjutsu: magic scrolls obtained during the event. One can be used twice. Gives special bonuses and you can choose only one of them.

剛 (pink): increases the player's current power by 20% until a castle has been fully conquered

幻 (purple): decreases the enemy's enemy power by 20% for one battle

気 (green): Onigiri cost for training reduced by 20% until the next action

鷹 (cyan): decreases chances of missing attacks to the enemy for one battle

貧 (white): decreases the strength of one castle boss (the gatekeeper) by 50%

開 (cyan): decreases the resistance of the locked door by 50%, lasts until a door is destroyed

解 (purple): decreases the resistance of the treasure box by 50% for one time

Ninjutsu cannot be used in the final castle (黒刃図城).

The command EXIT is used to close the event screen (same as when the time runs out).

Onigiri points obtained are lost when the player enters another castle. Events in the castles appear in specific points. The first castle (注都利阿流城) must be cleared before you can access the second and third castles (蒼刃図城 and 黄刃図城 respectively).

The following is a list of items that can be obtained throughout events in each castle:

Ninnin shichikenden (忍々七鍵伝)

The Ninnin shichikenden (忍々七鍵伝) event started on April 20th, 2017, and ended on July 2nd, 2018. It can be accessed in STANDARD mode, where it appears as a special folder that can be accessed on any stage. You can only enter it once a credit; once you confirm entering the event folder, you can't return to the regular song selection screen for that stage.) You can't switch between SINGLE and DOUBLE play, but level and difficulty restrictions are lifted.

Upon selecting the folder, players then choose a school, then a Dojo (流派) inside the school to unlock the song which represents that Dojo. Each Dojo is themed (e.g. a Scratch Dojo), and contains specific songs that fit the Dojo theme (in the previous example, the Scratch Dojo will contain scratch-intensive songs).

The Dojos are as follows, along with their unlockable songs and the type of songs included in them:

Fire school (炎雅流)

Happiness Dojo (幸福道場): HAPPY★RUSH: Songs with "HAPPY" in the title, genre, or artist.

Household Dojo (家庭用道場): Warrior: Songs that first appeared in CS versions of beatmania IIDX.

The one with the unusual gusts (風巻を極めし者): Quakes: Songs with "BREAK" in the genre. Only appears when all other Wind Dojos have been cleared.

Shadow school (影月流)

The one with the unusual shadow (影月を極めし者): Mare Nectaris: Final songs from past IIDX exclusive unlock events. Only appears when all other schools have been cleared.

After playing a song from a Dojo, players will move to another screen, where a seven-key keyboard is shown with different DJ ranks on each key, and enemy ninjas appearing on each key (how the DJ ranks on each key is determined needs confirmation, but it is speculated to be related to the accuracy for each key during the last song played). At this point, the player is given the option to raise any key rank corresponding to an active opponent to AAA (a key that is already at AAA can be chosen for this; if a choice is not made, one is randomly chosen). Then, players will cause damage to the ninjas, the damage being directly proportional to the DJ rank. If three Mystery Scrolls are used, all keys with a rank less than AA will be boosted to AA.

Defeating enemies will give the player the award the enemy is holding, if they have one. Enemies may hold BUZZ (1000 BUZZ), NORMAL and HYPER charts, and a special item to increase the 忍気 meter by 1/3. The ANOTHER chart will only be awarded once all seven enemies have been defeated.

Once the attack is finished, the player will return to STANDARD mode play for the rest of the credit (unless you're on the final stage).

If playing a mode other than STANDARD (one player only), playing songs will increase a special 忍気 meter, which will make attacks more effective. This will be consumed the next time the player enters a Dojo. The following bonuses are available:

Version up kinen gakkyoku koukan (バージョンアップ記念 楽曲交換)

A collaboration event with ノスタルジア FORTE, where by playing both beatmania IIDX 24 SINOBUZ and ノスタルジア FORTE in the same week from July 24th to August 6th, 2017, you will unlock both Surf on the Light in beatmania IIDX and Element of SPADA in ノスタルジア on August 1st and 8th, 2017.

EXPERT MODE

EXPERT mode was added to beatmania IIDX 24 SINOBUZ on March 16th, 2017. A handful of songs can be unlocked by playing their respective courses. For Dan courses, playing a SP course will also unlock the DP course's song of the same class and vice versa.

SECRET courses from beatmania IIDX 22 PENDUAL and beatmania IIDX 23 copula also return, with the same unlock requirements for their final songs, except this time around you don't have to clear the SECRET courses in order to unlock the songs; filling the gauge simply works.

Songs from Dan courses that have removed since its release have also been revived. In addition, the SP Kaiden course, which is taken from beatmania IIDX 14 GOLD CS, contains the original Kaiden-exclusive charts for VANESSA and KAMAITACHI, which have both been made † charts. As the Kaiden-exclusive charts for both songs were only available in Single, brand-new Double charts were created for them.

Kinran no omamori (金襴のお守り) unlocks

Kinran no omamori (金襴のお守り) items were added on December 14th, 2016 to provide access to songs from beatmania IIDX 23 copula that were not automatically unlocked. 金襴のお守り can be purchased with BUZZ, and require the basic course subscription.

To see the complete list of purchasable charts/songs, please see this page.

今日のイチオシ (Today's Featured Songs)

Every day, on all SINOBUZ machines, three songs are marked as "featured". You can see which ones are marked in the Data Entry window or in the songwheel menu. Playing all three of them in a day will grant you 300 bonus BUZZ.

WEEKLY RANKING

The WEEKLY RANKING feature in beatmania IIDX 24 SINOBUZ begins on November 30th, 2016. Weekly Ranking sessions last for a week, with Wednesday at 12:00 pm being the beginning and as well as the deadline in the successive week. Locked songs that appear as WEEKLY RANKING songs are available by default during that period.

This time, a STAR feature has been introduced. You earn a star (the day after a Weekly Ranking period for a song ends) if your score in the leaderboards for a specific Weekly Ranking song's chart is high enough. Note that stars depend on each song's chart, not on the whole song itself, which means you can earn up to three stars per Weekly song.

In the songlist menu, a bar shows your Weekly Ranking star progress on the chosen Weekly song's chart; the arrow determines your current position in the leaderboards:

Bronze star: if the arrow is located in the cyan section.

Silver star: if the arrow is located in the gray section.

Gold star: if the arrow is located in the yellow section.

Platinum star: if the arrow is located in the very small blue section (top 10 in the leaderboards).
